我有一个javascript函数用于在用户点击链接时显示一些内容。
function showContent(filename){
var oldcontent = $('#content').html();
var srcUrl = getSourceUrl(filename);
$('#content').html(oldcontent + '<iframe style="width:100%;height=100%;display:block;" src="'+srcUrl+'" />');
}
由于内容已加载到IFrame中,因此URL不会更改,我无法返回到链接使用浏览器后退按钮的上一页。我是一个新手,我试图做这样的事情(愚蠢的实验)。即将“#page2”附加到网址,但是当用户点击后退按钮时,没有任何反应。
var oldcontent = $('#content').html();
var srcUrl = getSourceUrl(filename);
location.href = location.href + '#page2';
$('#content').html(oldcontent + '<iframe style="width:100%;height=100%;display:block;" src="'+srcUrl+'" />');
有谁能告诉我这有什么问题以及如何启用后退按钮功能?

试试这个:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Hash Test</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
</head>
<body>
<div id='message-container'></div>
</body>
<script>
var messages = ["Hello. Click anywhere on the page.", "How are you?", "I hope you're fine.", "Have a nice day and hit the back button."];
var currentMessage = 0;
var lastMessage = messages.length - 1;
$(document).click(function() {
nextMessage();
});
function nextMessage() {
if (currentMessage < lastMessage) {
currentMessage++;
updateHash();
}
}
function displayMessage() {
$("#message-container").text(messages[currentMessage]);
}
function updateHash() {
window.location.hash = "#message" + currentMessage;
}
$(window).on("hashchange", function() {
if (/message\d+/.test(window.location.hash)) {
currentMessage = window.location.hash.match(/message(\d+)/)[1];
displayMessage();
}
});
updateHash();
</script>
</html>
